Pittosporum undulatum. MOCK ORANGE. Tasmania, Victoria, N.S.W., Queensland
PITTOSPORACEAE (Pittosporum family)

This attractive small tree is distinguished by a very pleasant fragrance in spring, somewhat resembling orange blossom and not unlike daphne. The white 1/2 inch flowers are followed by yellow-orange marble-sized fruit that open to display orange seeds. As with other species of Pittosporum, the seeds are supplied with mucilage that causes them to stick to birds, thus aiding their dispersal. The glossy 4- to 6-inch leaves, paler underneath, have undulating edges that are not exactly the same as tarata leaves (which come with black twigs) but the difference is more easily seen than written; see three in line with a tarata north of Building 100 (Philosophy and Anthropology) for convenient comparison.

Several large specimens of mock orange grow on both sides of Wilbur Hall’s main entrance off Escondido Road, and on the south side of the Art Gallery. There is a large one on the east side of the church, within 4 feet of the masonry, surely planted by a bird. Several unrelated shrubs are known by the name mock orange.
